付けしている。BACKGROUND OF THE INVENTION Conventionally, various pobin-divided choke coils have been provided as choke coils. This moves the bobbin 2 times parallel to the axis.
The bobbin is divided into sections, and one side of a roughly mouth-shaped core is held between each bobbin piece to form a roughly cylindrical bobbin, and a coil wire material is wound around the bobbin. The work of winding the coil wire is done by rotating the bobbin with it attached to the core.
If a terminal is provided on the bobbin in advance, the terminal will come into contact with the core during rotation, making it impossible to rotate the bobbin. Therefore, no terminal is provided on the bobbin, and the end of the coil wire material is temporarily fixed to the bobbin with adhesive. After the winding work is completed, the terminal block with the terminal is fixed to the bobbin, and the coil end is tied to the terminal and soldered.

付けと2度手間となり、また、からげ作業の自動化が困
難であるという問題点を有している。However, with the above manufacturing method, the end treatment of the coil wire requires two steps: temporarily fixing it to the bobbin with adhesive, tying it to the terminal, and soldering it, and there is also the problem that it is difficult to automate the tying process. It has points.

たうえでボビンを回転させて行なわれる。Means and Effects for Solving the Problems In order to solve the above problems, the method for manufacturing a coil component according to the present invention involves forming a conductive pipe on the flange of the bobbin in a conventional bobbin split type coil component. Press fit into the hole. The vibrator is press-fitted with its end exposed at a position that does not protrude from the outer peripheral surface of the collar. This is to prevent the pipe from interfering with the core when the bobbin is rotated in the subsequent coil wire winding process. The coil wire is wound by hanging the end of the coil wire on the exposed portion of the pipe and rotating a bobbin.

Since the terminal is then inserted into the pipe to make an electrical connection with the end of the wire, there is no interference between the vibrator and the core during the winding process, and there is no problem with the rotation of the bobbin. Of course, there is no need to temporarily fix the ends of the wire to the bobbin with adhesive as in the past, and automatic processing of the tying work is also facilitated. Further, a terminal block for attaching the terminals is not required, and a small coil component can be obtained.
